Cal Graeber
(1949-    )

Charles Calvert "Cal" Graeber, Jr., long-time California mineral dealer with his wife, Kerith, was born January 8, 1949 in Los Angeles County, the son of Marth Viault and Charles Graeber, Sr., a Redlands attorney. Cal first became interested in minerals through his father's business connections with the railroads. He attended the Colorado School of mines and graduated with a degree in Geology and Mining Engineering in 1972. That same year Cal was hired by Bill Larson to help run the Pala Properties mineral dealership, and in 1980 he left to form his own business, Cal Graeber Fine Minerals. He deals in fine mineral specimens, appraises collections, and provides professional cleaning and trimming services. Cal has traveled the world in search of specimens, and has been involved in various small mining projects, including operations in Tanzania for gem-grade spinel, and in Baja California for tourmaline; his current project (begun in 1999) involves mining for green fluorite at the Rogerley mine in Durham, England. Cal and Florida dealer Leonard Himes are exclusive agents for Coromoto Minerals, a company involved in mining tourmaline and other gem species at Mt. Mica in Oxford County, Maine. He is a well-known lecturer on gem and mineral topics.

Cal's wife, Kerith Sue Stiles, was born July 19, 1946 in Fallbrook, the daughter of businessman F. Paul Stiles. She learned about minerals from Bill Larson (Pala Properties) in the late 1960's, where she later met Cal. They were married in 1978, and she continued to work as an elementary school art teacher in Fallbrook until 1983, when she left that position to work full-time in the family mineral business. Over the years she has built a very fine and much-admired personal collection of Mexican minerals. She and Cal also have specialized collections of San Diego County minerals, quartz with inclusions, and general worldwide minerals.

Cal is a member of the Mineralogy Advisory Board at the San Diego Museum of Natural History, and is an honorary member of the San Diego Mineral and Gem Society. Cal and Kerith have been instrumental in forming the Fallbrook Gem and Mineral Society and in building the society's Rocky Crest Museum in Fallbrook.
